AI Technical Summary
Condensation inside locomotive headlights causes light scattering, reduced lighting intensity, and short circuits. Existing moisture-proof designs have structural defects and require frequent maintenance.
The system employs a dynamic pressure balance drying system, which includes a balance airbag, a circulating fan, an air dryer, and a humidity sensor. Through intelligent control, it achieves gas circulation dehumidification, creating a stable drying environment and avoiding frequent disassembly and maintenance.
It effectively eliminates condensation, reduces maintenance intensity, prevents parts from falling off, improves the stability of the lighting system and the lifespan of components, and reduces the total maintenance cost.
